她的笑刺痛我眼睛
[tā de xiào cì tòng wŏ yăn jīng]
'Her Laugh Pricks My Eyes.' Instead of a positive metaphor for being attracted, it might indicate someone's feeling towards a love interest or admiration - even seeing them happy may cause a bittersweet reaction. Or sometimes it can also be used in describing unattainable beauty who makes admirers feel pain out of adoration.
